   Sammanfattning : In many Western countries today, not least in Sweden, there are a lot of organizations that have great problems with sickness absence. The costs connected to the high rates of sickness absence have also risen to alarming levels. LÄS MER

5. 4. Whiteness and Fluorescence in Paper : Perception and Optical Modelling

   Författare :Ludovic Gustafsson Coppel; Per Edström; Håkan Olin; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paper Whiteness; Fluorescence Whitening Agents; Kubelka-Munk; light scattering; paper industry applications; Colour Appearance Models; CIECAM02; Monte Carlo; Optics; Optik;

   Sammanfattning : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This includes psycho-physical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.
